A detailed, dark and honest write. What particularly struck me was your questioning how you can support someone when you yourself are at breaking point. It's often the case that - by holding others up - we forget ourselves and become the ones who need the support. Sometimes, it's ignorance on others' part, sometimes it's selfishness, but we should always remember our own needs too.
Sorry for the ramble but this piece got me thinking.

Take care,

Ben
